CLOTH-CUTTER FOR CUSTOM TAILORS.

SPECIFICATION forming part of Letters Patent N 0. 741,930, dated October 20, 1903.

Application filed November 28, 1902. $eria1No. 133.046. (N0 model.)

To (LZZ whom it may concern.-

Be it known that I, PER E. SALIN, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cloth-Cutters for Custom Tailors, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description, sufficient to enable those skilled in the art to which it pertains to understand, make, and use the same.

This invention relates to a cloth-cutting machine provided with blades which are rapidly moved as'the machine is moved forward to cut the cloth.

The object of this invention is to obtain a cloth-cutter provided with shear-blades so related to each other that in the movement thereof when the machine is moved against a limited number of thicknesses of cloth a shearing cut will be obtained in substantially the same manner as when a limited number of thicknesses of cloth are cut by ordinary shears, thus enabling'a custom tailor to rapidly cut the cloth for a coat, a vest, or trousers.

In the drawings referred to as forming a part of this application, Figure 1 is a side elevation of the cloth-cutter embodying this invention, with the outer casing covering the driving parts of the shear-cutting blades cut away to expose such parts to view; and Fig. 2 is a front elevation of such cloth-cutter, with the front part of the casing thereof removed to expose the movable parts of the cloth-cutter to view. Fig. 3 is a sectional view on line 3 3 of Fig. 1 viewed in the direction indicated by the arrows; and Fig. 4is an elevation of a nut, which is shown in side or edge elevation in Fig. 3.

A reference-letter applied to designate a given part is used to indicate such part throughout the several figures of the drawings wherever the same appears.

A is the base of the cutter and is made of suitable shape to be slid around upon a table.

B is a standard extending upward from the base A, and C is the handle of the appa-' ratus.

D D are projecting lugs on standard B.

E is a casing inclosing the standard B and the actuating mechanism of the apparatus.

F is a vertical shaft journaled in the projecting lugs D D.

G G are cams secured on the shaft F to rotate therewith.

H is a universal joint at the upper end of the shaft F. 7 To produce rotation of the shaft F, an ordinary flexible shaft is secured to the universal joint H. I I are longitudinallymovable parts or frames mounted on the projections D D and provided, respectively, with pulleys J J, coming between the faces of the cams G G, so that by the rotation of such cams (by rotation of shaft F) such parts or frames'l I are movedlongitudinally. Rapidrotation ofshaft F in this manner produces rapid longitudinal movement of the parts or frames I I.

K K are steel blades respectively secured to parts or frames I I, as by the screws 1c 70. The blades K K are each provided with V-shaped recesses, the cutting edges L L thereof being at a slight angle from a horizontal plane and so arranged relative to each other that when the cutting edge L of one of the blades K is descending the cutting edge L of the other of such blades K is ascending, and cloth or other suitable article in the V-shaped recesses between such cutting edges is thereby cut with a shearing action-that is, as by a pair of shears. By this arrangement when blades K K ascend as Well as When such blades descend the shearing cut referred to is obtained, the cutting edge L on one of such blades cooperating in the downward movement thereof with the cutting edge L of the other blade K in the upward movement of such other blade. In the 'hereinbefore-described shear action of the cutting edges L L the blades K K are forced apart by the cloth which is being cut thereby, and to hold the blades K K in proper relation to each other I place the rollers M M against such blades, respectively, holding such rollers in position by the frames N N, which are secured to the upright B by the bolts 0 O.

P, Fig. 1, is a nut in which the screw-threaded part of the bolts 0 O engage. The frames N N are adjustably forced toward the cutting-blades K K by adjustment of the screwthreaded part of the bolts 0 O in the nut P,

the part of the bolts between the heads there-i of and the screw-threaded part moving longitudinally in frame N N and standard B.

Q is a slot in base A, in which slot the lower ends of blades K K descend. The purpose of nut P is to enable me to adjust the cuttingblades relative to each other by turning the screws 0 O in such nut.

I find in making a \l shaped recess in blades K K with the cutting edges L L, as described, rapid longitudinal movement of blades K K will rapidly cut one or more thicknesses of cloth, and a pattern or chalk-mark may be followed by moving the apparatus against such cloth.

To operate the apparatus, it is simplymoved around on a table by a person grasping the handle 0, so that the cloth to be cut is raised by the base A for the cutting edges L L to engage therewith, such cutting edges being arranged relative to the base A, so that the cutting edges L L are alternately above and below the upper surface of the base A, and

the cutting edges L L are arranged relative to such base A and cutting edges L L, so that when the cutting edges L L, respectively, rise above the upper surface of the base A they will be respectively met bya descending edge L L in such manner as to engage with and out the cloth which is between such cutting edges.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a cloth-cutting apparatus provided with movable blades and means to actuate such blades, rollers rotatably mounted in adjustable frames to come in contact with the blades, such blades respectively provided with a V-shaped recess and cutting edges therein between which cutting edges cloth is engaged and cut, in the operation of the apparatus; substantially as described.

PER E. SALIN.
